I know exactly what you're going through. I blew my knee out two years ago. I was back on the water for the first time last summer and it literally took me all summer to get back to jumping W2W. Even though I have been back to W2W jumps all summer this year, I am just now breaking through my mental wall and progressing.
I'm sure there are many things you can do that will help, but the best $13 you will ever spend on mental help is at:
http://www.mentalmanagement.com/A_WWIM_book.htm The book is called With Winning in Mind. It was written by my Father-In-Law, Lanny Bassham. He was a gold medalist in the 1972 Olympics for riffle shooting.
Don't let the riffle shooting thing deter you. His principles are valid for any sport. Currently he is coaching several PGA pro golfers, Olympic athletes, and even Navy Seals. Recently Meghann Major's coach contacted him for some books.
If you follow his instructions and apply them you will see IMMEDIATE results. Like I said, I had a very tough time jumping w2w after my knee injury. Despite the fact that Lanny is my father-n-law and I had access to his info anytime I wanted, at first I chose to try and get back to form on my own.
After wasting almost an entire summer I finally got a set of his audio CD's. I listened to them on my daily commute to work. After using his principles for one week I jumped and landed W2W on the very first attempt! The problem for me was that after I started jumping W2W again I stopped using his methods. I was no longer afraid, but my riding stopped progressing. I am now usuing his methods again and in just the past 3 weeks have really stepped up my riding.
His principles are very simple and straight forward, yet they are extremely effective. I hope this info can help you.
